AUXIIiTARY RO LL-FORMER FOR LINTER-CONDEIN'SERS.

Specification of Letters Patent.

Application filed July 5, 1917. Serial No. 178,607.

To all whom it may concern:

Be it known that 1, CHARLES E. PRATER, a citizen ,of the United States of America, residing at Fort Worth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in AuX iliary Roll-Formers for Linter-Condensers, of which the following is a specification.

My invention relates to improvements in roll forming attachments for linter condensers, and the object is to provide devices for cooperating with the roll formin core to make the forming of rolls more efficient. The linters are often short and the present way of forming the rolls of linters is not satisfactory because the rolls break so often and rolls cannot be formed large enough. The rolls require constant watching to start the roll or bat over the partly formed roll. The rolls often break and fall to the floor and when the linters once fall to the floor, they have to be mixed with the floor sweepings and can not be sold at as good or as high price as if they had not fallen to the floor. The waste and loss in this manner is considerable. The linter room is almost stifling with dust, and laborers have to be relieved for periods of time. The object of this invention is to provide a device for cooperating with the roll forming core by which the roll will be perfectly formed without the attention of a laborer. More linters will be saved to be sold at the price for the average linters and much labor and expense of labor will be avoided. The roll forming will require no attention except to start the bat on the core and to remove the roll when the desired weight has been reached. Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claim.

Reference is had to the accompanying drawings which form a part of this application.

Figure 1 is an end elevation of a condenser with the roll forming attachments mounted thereon. Fig. 2 is a plan view of the condenser drum.

The drawings show a condenser drum 1 of ordinary construction provided with a hat forming roll 2 mounted in bearings 3 whlch are mounted on a frame 4. The condenser is provided with the usual core 5 journaled in the swinging arms 6 which are plvotally connected to the bearing yokes 7, the latter havlng wings 8 for th1s purpose. The Hut ers come from the gins to the condenser drum 1 in the usual manner and pass under s the roller or bat former 2 where they are condensed and then passes on down to the core 5 where an operator has to start the hat on the core 5. Shortly after the linter bat begins to accumulate on the core, the roll former 9 will commence to cooperate with the core 5 and press the rOll thereon. The roll former 9 is journaled in bracket bearingslO which are attached to the frame 1. The roll former is close to the core 5 so that the roll former. 9 willcommence to cooper ate with the core shortly after the bat commences to wind on the core. The roll former might operate by friction against the linter hat, but I provide a drive for the roll former 9 so'that the roll former will be driven from the condenser drum 1. A shaft 11 is journaled in bearings 12 on the inside of the brackets 10. The bearings for the roll former 9 and for the shaft 11 are open bear ings and the roll former 9 rests by gravity in the bearings in the brackets 10 and the shaft 11 rests by gravity in the bearings 12. Friction wheels 13 are mounted on the shaft 11 and bear against the annular angle rims 141 on the drum so that these wheels 13 are driven by the drum 1. The wheels 13 bear against the periphery of the roll former 9 and drive the roll former by friction. The roll former 9 thus not only holds up the bat against the core 5, but exerts a pull on the bat to help to press the same on the core 5 and thus keep the roll smooth and relatively compact. This will keep the roll from breaking and make it possible to put the required weight of linters in the roll. The roll willneed no attention after the bat is once started on the core 5. The roll-former consists of a drum covered with Wire screen. As the roll increases in size the arms 6 will swing outwardly and upwardly to provide for the increase in size of the roll and the roll former 9 will continue to bear against the roll as it is formed and will help pull on the bottom of the roll to keep it going and to support the roll to keep it from breaking. There will be no linters to fall to the floor and be depreciated in value. When the roll is completed, it will be substantially in the position indicated by dotted outline in Fig. 1.

What I claim is, The combination with a condenser and its roll-forming core, of a roll-former 00- operating With said core to support and 5 press the bat thereon and to aid in pulling the bat thereon, and a friction drive for said roll-former consisting of a shaft and friction pulleys thereon bearing against and driven by said condenser and bearing against and driving said roll-former. 10

In testimony whereof, I set my hand, this 21st day of June, 1917.
